Capacity and Compatibility

This 32 GB DDR4 3200 MHz ECC SODIMM replaces Hynix HMAA4GS7AJR8N-XN and HMAA4GS7CJR8N-XN modules in microserver, server and workstation systems. The 260-pin unbuffered design operates at 1.2 V with CL22 latency for standard DDR4 voltage compatibility.

Sustained Load Behaviour

ECC functionality detects and corrects single-bit errors during continuous operation, maintaining data integrity across extended workloads. Rigorous quality-assurance testing validates reliable performance under prolonged memory-intensive tasks without buffering overhead.

Thermals and Power

The module runs at the standard 1.2 V DDR4 voltage and has no heat spreader, relying on system airflow for cooling. Unbuffered architecture keeps power draw low during normal use while the 260-pin SO-DIMM form factor fits standard laptop and microserver slots.

Questions about this item

Does the 1.2V 3200MHz 32GB ECC SODIMM run cool and quiet during continuous server workloads?

The module operates at standard 1.2V DDR4 voltage with no heat spreader; as a passive component it produces no noise and its thermal output matches typical DDR4 SO-DIMM power draw at this voltage and speed.

What must my laptop or microserver already provide to use this 260-pin DDR4 ECC SODIMM?

A DDR4 SO-DIMM slot that accepts 260-pin unbuffered ECC modules at 1.2V, with BIOS or firmware support for ECC operation and a memory controller qualified for 32GB density.

Will this CL22 32GB DDR4 3200MHz ECC module downclock reliably beside older DDR4 sticks I keep installed?

DDR4 modules negotiate a common speed and timing at boot; this stick will run at the highest frequency and latency supported by all installed modules and the platform memory controller.
